WARNING/CAUTION notices as used in this manual apply to hazards or

NOTICE
THE INFORMATION CONTAINED IN THIS DOCUMENT IS SUBJECT
TO CHANGE WITHOUT NOTICE.
As a manufacturer of wheelchairs, Invacare endeavors to supply a wide variety
of wheelchairs to meet many needs of the end user. However, final selection of
the type of wheelchair to be used by an individual rests solely with the user and
his/her healthcare professional capable of making such a selection.
WHEELCHAIR TIE-DOWN RESTRAINTS AND SEAT POSITIONING
STRAPS
Invacare recommends that wheelchair users NOT be transported in vehicles
of any kind while in wheelchairs. As of this date, the Department of
Transportation has not approved any tie-down systems for transportation of a
user while in a wheelchair, in a moving vehicle of any type.
It is Invacares position that users of wheelchairs should be transferred into
appropriate seating in vehicles for transportation and use be made of the
restraints made available by the auto industry. Invacare cannot and does not
recommend any wheelchair transportation systems.
WARNING
THIS SEATING SYSTEM HAS BEEN CUSTOM DESIGNED AND WILL BE
ASSEMBLED TO THE WHEELCHAIR BASE BEFORE DELIVERY TO THE
USER. THE INFORMATION CONTAINED IN THIS MANUAL IS FOR
MAINTAINING AND ADJUSTING THE SEATING SYSTEM. THERE ARE
VERY FEW ADJUSTMENTS THAT CAN SAFELY BE MADE BY THE
USER. IF THERE IS A PROCEDURE OR ADJUSTMENT THAT NEEDS TO
BE PERFORMED ON THE SEATING SYSTEM THAT IS NOT IN THIS
MANUAL, DO NOT PERFORM THAT PROCEDURE. HAVE THE
SEATING SYSTEM SERVICED BY A QUALIFIED TECHNICIAN.
The drive behavior initially experienced by the user may be different from
other chairs previously used. This Power Wheelchair has Invacares Sure Step
technology, a feature that provides the chair with optimum traction and
stability when driving forward over transitions and thresholds of up to 2-inches
for the M71 and 3-inches for the M91. The following warnings apply specifically
to the Sure Step Feature.
l Do not use on inclines greater than 9o.
l Do not use on inclines with wet, slippery, icy or oily surfaces. This may
include certain painted or otherwise treated wood surfaces.
l Do not traverse down ramps at high speed. Doing so will reduce traction
and increase stopping distance.
l The end users weight can materially affect traction on sloped surfaces.
Great care should be taken when traversing such slopes.
To determine and establish your particular safety limits, practice use of this
product on various sloping surfaces in the presence of a qualified healthcare
provider BEFORE attempting active use of this wheelchair. Other general
warnings listed within this document also apply.

CONTROLLER SETTINGS/REPAIR OR SERVICE
WARNING
Set-up of the Electronic Control Unit is to be performed ONLY by a
qualified technician. The final tuning adjustments of the controller may
affect other activities of the wheelchair. Reprogramming the controller
reduces the stability/controllability of the wheelchair. Other program
settings could cause the wheelchair to tip over resulting in serious injury to
the user and/or damage to the surrounding property. IF ANY

ANY WORK ON THESE UNITS, THE WARRANTY IS VOID.
GENERAL GUIDELINES
OPERATING INFORMATION
GENERAL WARNINGS
Performance adjustments should only be made by professionals of the
healthcare field or persons fully conversant with this process and the
driver's capabilities. Incorrect settings could cause injury to the driver,
bystanders, damage to the chair and to surrounding property.
After the wheelchair has been set-up, check to make sure that the
wheelchair performs to the specifications entered during the set-up
procedure. If the wheelchair does NOT perform to specifications, turn the
wheelchair OFF immediately and reenter set-up specifications. Repeat this
procedure until the wheelchair performs to specifications.
ALWAYS shift your weight in the direction you are turning. DO NOT shift
your weight in the opposite direction of the turn. Shifting your weight in the
opposite direction of the turn may cause the inside drive wheel to lose
traction and the wheelchair to tip over.
DO NOT shift your weight or sitting position toward the direction you are
reaching as the wheelchair may tip over.
To determine and establish your particular safety limits, practice bending,
reaching and transferring activities in several combinations in the presence
of a qualified health professional BEFORE attempting active use of the
seating system/wheelchair.
DO NOT attempt to reach objects if you have to move forward in the seat.
DO NOT attempt to reach objects if you have to pick them up from the
floor by reaching down between your knees.
